New Delhi: Climate change is increasing the intensity of forest fires, reducing vegetation and degrading natural habitats, forcing the wildlife to move out and come into conflict with humans, conservationists said on Friday (April 14). In its latest all-India tiger estimation report, released recently by Prime Minister Narendra Modi, the National Tiger Conservation Authority (NTCA) highlighted the “silent and surmounting” threats of climate change-related impacts on habitats and the loss of the quality of forests over time.
It added that climate change threatens the survival of tigers in the Sunderbans and is one of the major challenges facing the wildlife in the Western Ghats.
While the big cat population in the Sunderbans is steady, it has come down substantially in the Western Ghats where 824 tigers were recorded in 2022 against 981 in 2018.
Mohammad Sajid Sultan, the NTCA’s assistant inspector general of forests, said the wildlife is being affected by climate change with new pests and diseases emerging.
Rain patterns are also changing subtly and gradually rather than all at once. Reports have emerged of tigers moving to higher altitudes and overlapping territories with snow leopards, which has never happened before. This suggests that changes are occurring in the ecosystem, including shifts in monsoon rain patterns, more dry spells and forest fires, which will likely impact vegetation and organisms in the forest, including top predators like tigers, he said.
While empirical evidence is needed to fully understand the impact of climate change, it is undeniable that it is affecting wildlife, as well as the migration and breeding cycles of organisms, the official added.
Anish Andheria, the president of the Wildlife Conservation Trust and a member of the NTCA, said climate change is having a devastating impact on both wildlife and communities.
Climate change has led to erratic weather patterns, causing crop yields to diminish, and making farmers increasingly dependent on forests for their livelihoods. As a result, poor people are becoming even more reliant on forests for food and fuelwood, which in turn, is leading to a rise in human-wildlife conflicts, he said.
Moreover, the increasing frequency and intensity of forest fires, which is a direct result of drier weather conditions, is not only burning the undergrowth but the trees as well. This leads to the degradation of entire forests and causes animals to venture out of their territories and come into conflict with humans, the conservationist added.
Lead-Tigers for WWF-India Pranav Chanchani said climate change has varied effects on tiger habitats with the Sunderbans experiencing the most noticeable impact.
The rising sea level is gradually reducing the extent of mangrove habitats available for tigers and their prey, he said.
In other regions, climate change has been associated with forest degradation and a decrease in vegetation due to heat and water stress. More research is required to establish the connections between climate change, forest fires, vegetation and invasive plants, Pranav Chanchani said.
Given the increasing habitat fragmentation caused by linear development and land-use changes, he said the ability of large mammals to adapt and move in response to drastic weather events or climate-induced environmental changes is also becoming more challenging.

NDTV – Dettol have been working towards a clean and healthy India since 2014 via the Banega Swachh India initiative, which is helmed by Campaign Ambassador Amitabh Bachchan. The campaign aims to highlight the inter-dependency of humans and the environment, and of humans on one another with the focus on One Health, One Planet, One Future – Leaving No One Behind. It stresses on the need to take care of, and consider, everyone’s health in India – especially vulnerable communities – the LGBTQ population, indigenous people, India’s different tribes, ethnic and linguistic minorities, people with disabilities, migrants, geographically remote populations, gender and sexual minorities. In wake of the current COVID-19 pandemic, the need for WASH (Water, Sanitation and Hygiene) is reaffirmed as handwashing is one of the ways to prevent Coronavirus infection and other diseases. The campaign will continue to raise awareness on the same along with focussing on the importance of nutrition and healthcare for women and children, fight malnutrition, mental wellbeing, self care, science and health, adolescent health & gender awareness. Along with the health of people, the campaign has realised the need to also take care of the health of the eco-system. Our environment is fragile due to human activity, which is not only over-exploiting available resources, but also generating immense pollution as a result of using and extracting those resources. The imbalance has also led to immense biodiversity loss that has caused one of the biggest threats to human survival – climate change. It has now been described as a “code red for humanity.” The campaign will continue to cover issues like air pollution, waste management, plastic ban, manual scavenging and sanitation workers and menstrual hygiene. Banega Swasth India will also be taking forward the dream of Swasth Bharat, the campaign feels that only a Swachh or clean India where toilets are used and open defecation free (ODF) status achieved as part of the Swachh Bharat Abhiyan launched by Prime Minister Narendra Modi in 2014, can eradicate diseases like diahorrea and the country can become a Swasth or healthy India.
